Flotation Machine mainly consists of slurry tank, stirring device, inflator device, discharge mineralized bubble device, and motor. Slurry tank: It has a slurry inlet and a sluice device to adjust the surface of the slurry. It mainly consists of a tank body welded with steel plates and a gate plate welded with steel and round steel. Stirring device: It is used to stir the slurry to prevent ore from sedimenting in the tank. It is mainly composed of pulleys, impellers, vertical shafts, etc. The impeller is made of wear-resistant rubber. Inflatable device: It consists of a duct inlet pipe. When the impeller rotates, negative pressure is generated in the impeller chamber. Air is sucked through the hollow pump pipe and dispersed in the slurry to form a bubble group.
This kind of slurry with a large number of bubbles is formed by the impeller. The rotational force is quickly thrown toward the stator, further refining the bubbles in the pulp, and eliminating the rotational movement of the pulp flow in the flotation cell, resulting in a large number of vertically rising microbubbles, providing the necessary conditions for the flotation process. Excludes the mineralized bubble device: it is to scrape the foam floating on the groove surface, mainly driven by a motor reducer, reducer drives the scraper composition.
The flotation machine has a large amount of inhalation and low power consumption; each tank has the triple functions of suction, suction and flotation, and it is a self-contained flotation circuit. It does not require any auxiliary equipment and is configured horizontally to facilitate the change of the process. The slurry cycle is reasonable. , Can minimize the coarse sand sedimentation; With the automatic control device of the ore slurry surface, easy to adjust; The flotation machine impeller with backward and backward type of the upper and lower blades, the mining flotation machine on the blade to produce slurry on the circulation, the next blade under the pulp cycle.
During flotation, the ups and downs of minerals are almost independent of mineral density. For example, chalcopyrite and quartz, the former density of 4.2, the latter is 2.68, but the heavy mineral chalcopyrite is very easy to float, but quartz sinks to the bottom. The research found that the floatability of minerals is related to their affinity for water. Any mineral that has a high affinity with water and is easily wetted by water is difficult to attach to bubbles and is difficult to float. The minerals that have low affinity with water and are not easily wetted by water are easy to float.
